CLINTON, Tenn. - He suspected his live-in girlfriend of planning an affair, and when he saw a picture of a man he didn't recognize on her Facebook page, it set him off, according to reports.

Lowell Turpin "angrily demanded to know who the male was," an Anderson County Sheriff's Department incident report states.

The answer, his girlfriend told him: presidential contender Mitt Romney.

Upset at the woman's "attempting to communicate with friends through her Facebook account," Turpin jerked her laptop computer from her grasp, smashed the machine into a wall, and then hit her in the face with his fist, according to reports.

The 40-year-old Turpin remains in the Anderson County Jail, charged with domestic assault in connection with the July 22 incident in Anderson County's Claxton community.

The woman told a deputy that Turpin "has been violent toward her multiple times over several years."
